The Sun Hydraulics DNCALAV228 (DNCALAV228) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting. This characteristic is especially crucial in pilot control circuits where maintaining fluid integrity is key. The valve is designed to operate with port 3 as the inlet and port 1 as the tank; however, while reverse flow is possible, it may not deliver the same performance and is not recommended. With a capacity of 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar, this valve can handle demanding tasks efficiently. The response time is typically around 50 ms, ensuring quick and reliable operation. The DNCALAV228 also boasts a maximum valve leakage at 110 SUS (24 cSt) of only 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), highlighting its effectiveness in maintaining system integrity. The solenoid tube assembly of this model is fatigue rated for high-pressure service up to 5000 psi (350 bar), making it suitable for heavy-duty applications. Additionally, the valve's wet armature design means that the working fluid surrounds the armature; this design consideration should be noted as prolonged coil energization can lead to fluid degradation in certain conditions. A variety of coil termination and voltage options are available for this model, enhancing its adaptability to different system requirements. These options include configurations with or without surge protection and coils that are interchangeable with other Sun Series 1 solenoid products. Furthermore, environmental protection for the coils can be enhanced through additional weatherized kits. This model also incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures consistent performance and longevity of the component within hydraulic systems.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
